sysadmins/webmasters of fedi:
I am looking for suggestions of which search engine crawlers I should consider permitting in my robots.txt file.
There can definitely be value in having a site indexed by a search engine, but I would like to deliberately exclude all of those which are using the same data to train LLMs and other genAI. More specifically, I would only like to allow those which have an explicit stance against training on others data in this fashion.
Currently I reject everything other than Marginalia (https://marginalia-search.com/). Are there any others I should consider?
